Alan is a middle school student. It's Sunday morning. He doesn't go to school. He wants to play with his friends in the morning. He is looking out of his bedroom.
It is raining hard and windy outside. He is worried that it will rain for a long time, and really wants the rain and wind to stop right now so that he can go out to meet his friends.
The rain stops in the afternoon. He comes out from his house. The air is clean. The trees and houses are clean, too. Everything is new. The clouds go, and the sun comes out. A big rainbow crosses the sky. People here do not often see a rainbow.
So Alan asks his father, "How does the rainbow form (形成)? "
"When the sun shines the raindrops (雨滴), the rainbow comes out. From this, we can learn: in most cases, we can't see rainbows if it doesn't rain, " Alan's father tells him.
"I see, " says Alan. Then he calls his friends and asks them to go out.
Alan and his friends have a good time. Alan is very happy.
He learns from the rain: when we meet bad things, just enjoy them, and everything will be better.
